Abstract

A method for making an ink jet recording element comprising simultaneously coating on a support the following layers in order: a) a nonionic, water-dispersible, condensation polymer gloss-enhancing layer; and b) an ink receptive layer for an ink jet image.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A method for making an ink jet recording element comprising simultaneously coating on a support the following layers in order: a) a nonionic, water-dispersible, condensation polymer gloss-enhancing layer; and   b) an ink receptive layer for an ink jet image.   
     
     
       2. The process of claim 1 wherein said support is paper. 
     
     
       3. The process of claim 1 wherein said ink receptive layer comprises gelatin. 
     
     
       4. The process of claim 1 wherein said ink receptive layer is present in an amount of from about 5 to about 60 μm. 
     
     
       5. The process of claim 1 wherein said gloss-enhancing layer is present at a thickness of from about 2 to about 5 μm. 
     
     
       6. The process of claim 1 wherein said condensation polymer is a block copolymer of a polyester and a polyether. 
     
     
       7. The process of claim 6 wherein said block copolymer is poly[terephthalic acid-co-isophthalic acid-co-ethylene glycol-block-poly(ethylene glycol)]. 
     
     
       8. The process of claim 1 wherein an overcoat layer c) is also simultaneously coated with layers a) and b). 
     
     
       9. The process of claim 8 wherein said overcoat layer comprises a cationically-modified cellulose ether. 
     
     
       10. The process of claim 9 wherein said cationically-modified cellulose ether is poly[β-D-1,4-anhydroglucose-g-oxyethylene-g-(2'-hydroxypropyl)-N,N-dimethyl-N-dodecylammonium chloride].
